Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00085 | $0.01941 |
| Opus 5 | $0.00043 | $0.00971 |
| Sonnet 5 | $0.00017 | $0.00388 |
| Haiku 4.5 | $0.00009 | $0.00194 |
Grade A, and why
game-ai scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Game AI: decisions, steering, and pathfinding
Build believable NPC behavior from three separable layers: decide (what to do), steer (how to move there), and path (how to route around the map). Keep them decoupled — a behavior tree picks a target, the pathfinder produces waypoints, steering follows them. This skill teaches the engine-neutral algorithms; bind them to your engine via the related skills below.
When to use
- Use when implementing enemy/NPC logic: patrols, chase/flee, guard states, group movement, or "find a path to the player".
- Use to choose between an FSM (few clear states), a behavior tree (many reactive behaviors with priorities), or steering (smooth local movement).
- Use when integrating pathfinding: A* on a grid/graph, or driving an engine navmesh agent.
When not to use: for the engine's concrete navmesh/agent API and baking,
use unity-navmesh, unreal-behavior-trees, or Godot's NavigationAgent2D/3D
(see that engine skill). For movement/collision feel, use physics-tuning. For
spawning waves along lanes, see the tower-defense genre skill.
Core workflow
- Pick the decision model by complexity. 2–5 states with obvious transitions → FSM. Many behaviors, priorities, interruption, reuse → behavior tree. Continuous "how strongly do I want each option" → utility scoring.
- Separate decision from motion. The decision layer outputs an intent (target position, action). Steering or pathfinding turns intent into motion.
- Path on the right graph. Grid tiles, waypoint graph, or a baked navmesh. Fewer nodes = faster A*. Prefer the engine's navmesh for 3D; A* on a grid for tile games.
- Steer along the path, not straight to the goal — follow the next waypoint, advancing when close, so agents round corners.
- Recompute paths sparingly. Pathfind on a timer or when the goal moves a tile, not every frame. Cache the path; only the waypoint index advances.
- Verify by observation. Watch the agent: does it reach the goal, get stuck on corners, oscillate between states? Draw the path and current state on screen while tuning.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

game-ai is a skill published in the GitHub repository gamedev-skills/awesome-gamedev-agent-skills (952 stars, last pushed 2d ago), licensed Apache-2.0. It adds 85 tokens to every session and 1,941 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
assets-get-data
Get asset data from the asset file in the Unity project — every serializable field and property. Supports token-saving path-scoped reads via paths or viewQuery. Use 'assets-find' to find the asset first.
gameobject-set-parent
Reparent a batch of GameObjects under a new parent in the currently opened Prefab or active Scene. Per-item failures are reported in the returned status string instead of aborting the batch. Use 'gameobject-find' to locate the GameObjects first.
unity-version-split
Split a C# file into Unity 6.5+ and pre-Unity 6.5 variants. Use when a file needs different implementations for different Unity versions due to API changes (e.g., EntityId vs int, GetEntityId vs GetInstanceID).
profiler-save-data
Save a snapshot of profiler-derived stats (status + memory + rendering + script + frame capture) to a JSON file. Built-in Unity APIs only.
assets-shader-list-all
List all shaders available in the project assets and packages, sorted by name. Use this to discover a valid shaderName for 'assets-material-create'.
profiler-stop
Disable Unity's runtime profiler. Idempotent — calling when already disabled returns the current disabled state.
